متن کاملMalignant transformation of osteoblastoma: study using image analysis microdensitometry.
AIM To determine if the malignant transformation, as perceived histologically, in a case of osteoblastoma from the right femur, was also expressed as a quantitative change in nuclear DNA during tumour progression over five months. METHODS Nuclear DNA microdensitometry by computer image analysis was used to acquire relative DNA distribution patterns. Tissue had been removed on four separate oc...

The clinical, radiological and pathological features of two cases of an osteogenic tumour with long survival are described. The tumours have the histological pattern of benign osteoblastoma with other more cellular and aggressive features suggestive of a low grade osteosarcoma. They are locally invasive but the absence of metastases indicates that separation from both entities is justified clin...
متن کاملOsteoid osteoma and osteoblastoma.
Osteoid osteoma and osteoblastoma are commonly seen benign osteogenic bone neoplasms. Both tumors are typically seen in the second decade of life, with a notable predilection in males. Histologically, these tumors resemble each other, with characteristically increased osteoid tissue formation surrounded by vascular fibrous stroma and perilesional sclerosis. However, osteoblastomas are larger th...
متن کاملOsteoblastoma of the spine.
A retrograde analysis of 64 spinal osteoblastomas treated by surgery during the period 1963 - 2005 has been made. Spinal osteoblastomas were presented in 36% of all skeletal localizations. There were 44 male and 20 female patients. The average age of patients at the time of surgery was 14 years. Localizations of the osteoblastomas were cervical spine in 8 cases, dorsal spine in 16 cases, lumbar...
